DifficultyEasy ≈ PLA
Which shore hardness?
Same line, same formula — only firmness differs. See each hardness in a real print, then pick by what you're printing.
Multi-color printing on Bambu AMS — steadier feeding, lower tangling risk.

Low moisture
Four common pitfalls, solved
Know the cause before it happens.
Moisture
SYMPTOMIncreased stringing, bubbles/rough surface, nozzle hissing
CAUSETPU absorbs moisture quickly
FIXDry at 70–75 °C for 4 h before printing; seal + desiccant; re-dry after 1–2 days exposed
Stringing
SYMPTOMThin wisps left on travel moves
CAUSEHigh temp / low retraction / moisture / Z-hop
FIXDry first → drop 5 °C → enable Combing → disable Z-hop → add slight retraction; clean with a heat gun
Soft-filament feeding
SYMPTOMExtruder gear clicking, filament wrapping the gear
CAUSEToo much retraction / gear too tight / sudden speed changes
FIXLess retraction (0.5–1.5 mm), loosen the gear, prefer direct drive, keep speed uniform
Layer adhesion
SYMPTOMBreaks along layer lines when bent
CAUSELow temp / strong fan / too fast / moisture
FIXRaise 5–10 °C, fan <30%, slow down, dry

FAQ
How to store TPU filament?
· 密封袋/密封盒 + 干燥剂（硅胶）
· 湿度 > 40% 的环境建议使用干燥箱打印
· 暴露空气中超过 1–2 天就需要重新干燥
· 远离阳光直射和高温
黄金法则：取出打印后立即放回密封袋并封好口。
What is the shelf life of TPU?
· 干燥密封状态：1–2 年没问题
· 暴露潮湿环境：几天就会吸湿到影响打印的程度
过期或严重受潮的 TPU 不一定报废——充分干燥（55°C / 6小时）后仍可使用。判断标准：打印时无嘶嘶声、表面无气泡。
Can I mix TPU from different brands?
物理上可以（都是 TPU 基材），但不同品牌的打印参数可能差异较大：
· 不建议在同一卷上拼接不同品牌的线材
· 切换品牌时建议重新做温度塔测试
· 同一打印任务中尽量使用同一品牌同一批次
Can TPU prints be post-processed?
· 打磨：不推荐——TPU 太软，砂纸会把表面拉毛
· 喷漆：用柔性漆（flexible paint）
· 粘接：TPU 专用胶或火焰处理 + 聚氨酯胶
· 去拉丝：热风枪/打火机快速过一遍（最有效方法）
· 涂层：聚氨酯清漆可以增加表面硬度和耐刮性
Is TPU resistant to oil and chemicals?
· 良好抗性：大多数油类、油脂
· 可耐受：弱酸弱碱、汗液、雨水、普通清洁剂
· 不耐受：强酸强碱、某些有机溶剂（如 THF、DMF）
日常使用中，TPU 对汗液和雨水的耐受性很好，非常适合穿戴类应用。
